The changes were a response to the "evolving new coronavirus situation," according to an announcement on the Embassy's official website. All appointments from March 19 onwards have been canceled, it said.
New appointments for non-immigrant visa applicants will be opened as soon as the Embassy and Consulate General could manage, while urgent cases could contact the Embassy and Consulate directly, it said.
Visa processing procedures for immigrant visa applicants would resume at a future notice, and rescheduling would be possible for those who have already missed previously scheduled appointments, it added.
